Heidi, I see you have 2 threads going here. It might be best to consolidate so there is continuity. I replied on the other one earlier.
As has been said, this is a big decision and requires you to be armed with all of your pathology reports, second opinions, consultations. Be sure to have your questions (and the answers!) written down. Keep records of everything. Most hospitals have "tumor boards" where your case is presented to a group of doctors who discuss treatment options and recommendations. It is a decision only you can make once you have all the facts but alot of people will give input so you can be informed.
I opted for a double mastectomy but am ALOT older than you and had a suspicious area in the other breast (it was benign). I do not regret the decision but I miss the breast!
Keep the faith. We will support you.
It would help if you put your stats in your signature.
